Yêu cầu trực tuyến →— sulphide/oxide copper gold vein deposit Until June 2009 the sulphide and oxide minerals were respectively recovered by the well established xanthate flotation of sulphides and acid leaching of soluble oxide copper The mixed transitional sulphide/oxide ores were stockpiled in the absence of an economic processing route due to their poor
— of copper and 160 000 ounces of gold Ore mined from the epigenetic vein hosted deposit is classified into three ore types based on the extent of oxidation and supergene enrichment Sulphide oxide and mixed ore are fed to separate mineral processing circuits tailored for recovery of the dominant copper minerals in each After
Yêu cầu trực tuyến →— Given that Congo is the biggest cobalt supplier I will briefly share several efficient cobalt processing methods widely used in the cobalt mines located in the Katanga copper cobalt ore belt as an example Crushing process Severe sliming is a distinctive feature of copper oxide ore The local rainy season November to March has heavy rainfall
Yêu cầu trực tuyến →— Types of copper ore Oxides As mentioned copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade However in some cases low grade copper oxide ores can still be economically mined because they can be processed at a lower cost than copper sulfide ores Oxidized copper orebodies may be
Yêu cầu trực tuyến →— T he copper mining industry is reaching a turning point Surface oxide deposits are depleting and copper miners are turning their attention to untapped sulfide ores found deeper underground However sulfides require more expensive processing techniques since they are not responsive to standard technologies that are used in oxide
Yêu cầu trực tuyến →— Copper ores can be divided into various types such as copper sulfide ores copper oxide ores and mortar copper ores The beneficiation methods used in these types of ores are also different such as copper sulfide ores The beneficiation of these ores requires grinding and flotation and leaching steps The raw ore is ground and then goes
Yêu cầu trực tuyến →— The Introduction of Copper Ore Processing Equipment Copper Ore Crushing Equipment Copper Ore Crusher; Copper ore crusher is for the extraction of copper ore coarse crushing and the equipment that is based on the advantages of the jaw crusher and combined with the special crushing equipment of copper mine produced by
